PARTITION STRIP FOR COMPOSITION FLOORING Application filed January 31, 1929. Serial No. 386,485.

This invention relates to partition strips for composition flooring, such as terrazzo and the like, and aims to provide a strip that is formed with positive means for anchoring it into the cement bed, which is usually laid as a foundation for the composition flooring,

and to absolutely prevent the strip from working loose.

An object of the invention is to provide the strip at its opposite sides with pairs of coacting struck out wings to provide a cement receiving trough within the wings and strip, as well as slots in the strip through which the cement will pass when the strip is properly placed in the cement bed to prevent move ment of the strip. The cement hardening between and in back of the wings forms lugs in the hard bed that so engage the wings of the slots as well as within the trough to abpolutely prevent the strip from working oose.

An additional object is to provide anchorage means that will not absolutely necessitate the forcing of the anchor entirely into the ocment bed. The anchor is such that .even though the lower portion only thereof is forced into the cement, an absolutely positive anchor will be had until the terrazzo is laid.

A further and additional object is to provide a partition strip of this character, wherein the anchorage means is an integral part thereof, and that can be struck from the strip by not more than two simple mechanical operations with the result that the complete strip can be manufactured at nominal cost.

In the drawing wherein like reference characters indicate corresponding parts throughout the various views:

Figure 1 is a fragmentary perspective and sectional view of a partially laid composition flooring, the surfacing material not being illustrated, so as to more clearly bring out the manner of disposing the partition strips in the cement base, said partition strips being constructed in accordance with this invention.

Figure 2 is a fragmentary section through the complete floor, and through my improved partition strip.

Figure 3 is a fragmentary plan. view of the 50 improved strip.

Figure 4 is an upper edge elevation thereof, and

Figure 5 is a fragmentary diagonal section taken through the strip on substantially the line 5-5 of Figure 3.

Now, having particular reference to the drawing, the strip which is of brass, copper or other suitable material is designated 5, and obviously, it is of any desired length, width and thickness, as well as being of any suitable design. The various anchors are formed at spaced points throughout the length of the strip and are alternately at opposite sides of the strip, as more clearly disclosed in Figures 2, 3 and l. Furthermore, these anchors are beneath the center line of the strip, and in each instance, they are formed by providing the strip with spaced pairs of relatively wide V-shaped incisions 6-6, the material between which is bent outwardly and upwardly to provide a pair of complemental wings 7-7, which are bent to an angle of approximately with respect to the strip as illustrated in Figure 5. As will be noted in Figure 3, the position of the incisions is such as to provide, after the wings have been bent to position, a pair of slots 8-8, the apices of which are unopposed, and which slots are preferably at an angle between the longitudinal and transverse planes of the strip, the vertical legs thereof converging towards their upper ends as illustrated in Figure 3.

The co-acting wings 7-7 will combine with the strip to provide a somewhat V-shaped cement receiving trough 9, and the cement hardening therein will form a lug integral with the base and locked within the confines of the wings, thus anchoring the strip in the cement.

It will, be seen that the ends of the slots as well as the ends of the wings are between the center line of the strip and the lower edge thereof, and in addition to the cement entering the various pockets of the strip, it will pass through these slots as well as through the wings so as to positively secure the strip within the cement. Even though the entire area of the anchors is not forced into the cecent base A, in Figure 2, a sufficient amountwill pass into the pockets, as well as through the slots to provide a positive anchor until the terrazzo or other composition flooring is laid.

It will thus be seen that I have provided a novel, simple and highly efiicient partition strip for composition flooring, that is well adapted for all of the purposes designated, and even though I have herein shown and described the strip anchors as of a certain design and formation, it is nevertheless to be understood that some departures may be had without affecting the spirit and scope. of the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

1. In a partition strip for composition flooring, a pair of adjacent wings struck from the strip and bent upwardly into spaced relation with the strip, said adjacent wings c0- operating with the strip for forming a cement receiving pocket, the lower ends of the wings being in close spaced relation, while the upper ends thereof are relatively widely separated to provide a substantially conical shaped pocke 2. In a partition strip for composition flooring, wherein the same is formed With adjacent pairs of spaced relatively V-shaped incisions, the material between the incisions of each pair being bent outwardly and upwardly to provide spaced wings, which cooperate with the strip to present a cement receiving pocket, the apices of the incisions being unopposed, and said incisions being substantially intermediate the transverse and longitudinal axes of the strip, so as to provide canted slots within the strip when the wings are struck therefrom.

In testimony whereof I afiix my signature.
